Novel immune cell population may trigger inflammation in multiple sclerosis and other brain disorders

Posted: 01 Dec 2021 05:39 PM PST

A group of immune cells that normally protect against inflammation in the gastrointestinal tract may have the opposite effect in multiple sclerosis (MS) and other brain inflammation-related conditions, according to a new study. The results suggest that countering the activity of these cells could be a new therapeutic approach for such conditions.

Researchers develop model for treating HIV/AIDS, depression

With a shortage of mental health professionals, an international team trained nurses to treat clinically depressed HIV-positive people in South Africa -- the HIV/AIDS capital of the world.

Eye imaging technology breaks through skin by crossing beams

Posted: 01 Dec 2021 01:20 PM PST

Biomedical engineers have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The new 'dual-axis' approach opens new possibilities for OCT to be used in applications such as spotting skin cancer, assessing burn damage and healing progress, and guiding surgical procedures.

Magnetic resonance imaging (MRI) and artificial intelligence (AI) can detect early signs of tumor cell death after novel therapy

Posted: 01 Dec 2021 12:01 PM PST

A recent study demonstrates that magnetic resonance imaging (MRI) and artificial intelligence (AI) can be used to detect early signs of tumor cell death in response to a novel virus-based cancer therapy.

New computational approach predicts chemical reactions at high temperatures

Posted: 01 Dec 2021 05:51 AM PST

Engineers invent 'green' method that combines quantum mechanics with machine learning to accurately predict oxide reactions at high temperatures when no experimental data is available; could be used to design clean carbon-neutral processes for steel production and metal recycling.

Why cannabis smells skunky

Posted: 01 Dec 2021 05:51 AM PST

As cannabis is legalized in more areas, it has become increasingly popular as a medicinal and recreational drug. This plant produces a pungent, skunk-like odor that is pleasing to some but repulsive to others. Now, researchers have discovered a new family of prenylated volatile sulfur compounds (VSCs) that give cannabis its characteristic skunky aroma. The findings open up opportunities to investigate the molecules for medicinal benefits, the researchers say.

Shrinking qubits for quantum computing with atom-thin materials

Posted: 30 Nov 2021 02:39 PM PST

Current approaches to create superconducting qubits for quantum computers yield chips that are substantially larger than those found in classical computers. To shrink things down, researchers have taken advantage of atomically thin, 2D materials to construct the necessary capacitors for superconducting qubits. Their two-qubit chip is 1,000x smaller than those made with conventional fabrication techniques.

Altered DNA repair and DNA damage in neurodegenerative conditions

Posted: 30 Nov 2021 02:39 PM PST

Researchers have confirmed a link between altered DNA repair and increased DNA damage associated with spinocerebellar ataxia type 7 (SCA7), a debilitating, sometimes deadly neurodegenerative condition causing movement disorders. Their work also revealed a potential therapeutic target for the currently incurable and difficult to treat condition.

Distortion: Researchers discover new strategy for antibodies to disable viruses

Posted: 30 Nov 2021 08:25 AM PST

It is widely understood that antibodies neutralize viruses by latching onto their surfaces and blocking them from infecting host cells. But new research reveals that this barrier method isn't the only way that antibodies disable viruses. An international team of researchers has discovered that antibodies also distort viruses, thereby preventing them from properly attaching to and entering cells.
